Openflight databases seem to use this user-data at the root

UTM-databases.
Unfortunately this class doesn't seem to have a serializer
for the osgXYZ file formats. What is the best way to add such
serialization capabilities?
Been a very very long time since I heard mention of the
osgSim::GeoographicLocation class... just been sitting there
quietly minding it's own business.
The issue right now is, that I somehow have to distribute the
lat,lon origin in some OpenFlight centric workflow. I could
totally do this differently by transforming the information into
my own format.
Looking at the implementation now the two parameters that need to
be serialized at the latitude and longitude paramters. If these
used the setName()/getName() convention then it'd be easy to add
serializers using the standard ADD_DOUBLE_SERIALIZER( Name, 0.0);
serializers (for instance see the usage in
src/osgWrappers/serializers/osg/ ).
As these don't follow the setName/getName() one will either have
to write a custom serializer for it or simply change the naming
across to the setName()/getName() convention that the almost all
of the OSG uses. I'd be inclined to do the later. Then just add
the GeographicLocation serializers to the
src/osgWrappes/serializers/osgSim. This would mean that the
change could only be add to OSG master and no backported to
OSG-3.4 or OSG-3.2 as the ABI would change, but personally I'd be
happy with this.
I'll try to do this then and present the submission when I find
the time.
The other route which would with recent OSG versions would be to copy
the GeographicLocation data to the a Node's UserValue i.e.
node->setValue("latitude", geographicLocation->latitude());
node->setValue("longitude", geographicLocation->longitude));
The values then would be serialized automatically.
That's what I'm doing right now. It would be nice ot to lose the data
when using osgconv however. So thanks for the pointer but I provide a
general fix for it.
Robert.
